Hi. Welcome.
These appear to be mostly modern, from the 90's and early 2000's.
The white with black speckles might be a Vacor Dalmatian. If that's what it is, it's a discontinued style, so you might find some interest in it. I can't guess the value though. I may not ever have seen one for sale. https://www.billes-en-tete.com/detail.php?id=112
The black and yellow one appears to be a modern Marble King.
The very large one would be a Vacor Serpent. The size alone might make that worth a few dollars. https://www.billes-en-tete.com/detail.php?id=51
The ones with blue and yellow would likely be Vacor. I have seen them in packages with an assortment of styles, but I've never seen a name for the style.
The Coca Cola marble is probably not officially associated with the Coca Cola company. Some people paid companies fees to get permission to make marbles with their trademarked images. But many logo makers didn't legally get the rights to print the logo. I don't know how we would tell on that. It's a fun marble that a logo marble collector might like, but I don't know what the value would be.
I don't think there is a lot of monetary value in the group but if you listed them on ebay in small groups, you might get some bidding action.
